What OLV Means in Advertising, and Why It Is Not the Same as CTV

The actual difference: device and behavior, not just screen size

OLV plays on personal devices — phones, tablets, laptops — inside an active browsing session. The viewer is often doing something else at the same time, has the option to skip or scroll past in many formats, and is watching alone more often than not. CTV plays exclusively on a television, through a streaming app, typically in a lean-back living-room context, and it's overwhelmingly non-skippable with sound on by default under current industry ad-format guidelines. Those aren't cosmetic differences — they change what creative has to do to work, and they change how a completion rate should be read, since a completed OLV view and a completed CTV view represent very different levels of committed attention.

Screen size correlates with these differences without causing them — a tablet playing OLV in landscape mode can look almost identical to a small connected-TV setup, yet the ad experience underneath is still governed by whether the platform treats it as skippable, browsing-context inventory or non-skippable, chosen-content inventory. Judge a placement by its actual mechanics, not by the size of the screen it happens to be displayed on.

Why the confusion happens

Both formats often live inside the same DSP, sometimes even the same campaign wizard, which makes it easy to treat them as one buy with two delivery options. Amazon DSP itself reaches both: online video served in the Amazon shopping and browsing experience or on third-party apps and sites, and CTV inventory across Prime Video, Fire TV Channels, Twitch and, more recently, Disney's bundle and Netflix. They share infrastructure and, often, a targeting audience — but they don't share a viewing context, and a media plan that treats a 15-second OLV cut and a 15-second CTV cut as interchangeable is skipping a real creative decision.

The naming doesn't help either. "Video" gets used as an umbrella term across ad platforms generally, and a campaign objective simply labeled "video" in a DSP interface can span both formats without flagging the distinction at all. The only reliable way to know which one a given line item is actually buying is to check the supply source directly, not the objective label.

Reporting dashboards compound the confusion further when they default to a single “video” rollup metric across every placement type in an account. Splitting that rollup into its actual supply sources, even when the dashboard's default view doesn't make it easy, is worth the extra click.

A worked example

Split a $16,000 test budget $6,000 to OLV and $10,000 to CTV. OLV inventory generally runs at a lower CPM than premium CTV — a reasonable planning range is $10–$20 for OLV against the $20–$50 range reported for premium streaming — so that split buys roughly 400,000–600,000 OLV impressions against 200,000–500,000 CTV impressions depending on where each lands in its range. Judge completion rate separately and expect it to differ meaningfully: industry benchmarks put CTV completion at 90%+, often above 95% for 30-second non-skippable spots, while combined PC and mobile video completion averages closer to 62% — not because CTV creative is better, but because the format removes the skip option and sits in a more attentive viewing environment.

Worth flagging on the cost side, since OLV specifically is where it applies: a $0.41 CPC figure circulates widely in this category. It's a real online-video-only number, not a blended DSP figure — across 30 advertisers in our own book in July 2026, the account-wide blended CPC across every format including CTV was $1.42. Quoting $0.41 as if it describes the whole streaming and video book, rather than OLV specifically, is the exact mixup this page exists to prevent.

What to do when the two get confused in reporting

If a blended "video" report shows a completion rate that doesn't match either format's typical benchmark, check whether OLV and CTV delivery are being combined into one line — a blend of 62%-range OLV and 95%-range CTV completion produces a number that misrepresents both. If a creative built for OLV is being reused unchanged on CTV, check whether it was designed assuming a skip option exists; creative built to earn attention in the first three seconds because a viewer might skip behaves differently than creative built for a captive, non-skippable audience, and the difference is often visible in completion-rate performance once it's actually broken out by format.

The common mistake

The mistake is treating "video" as one line item and one creative strategy across OLV and CTV, because both are technically video and both run through the same DSP. They're different formats with different viewer psychology, and budgeting, creative and measurement should all be built around that difference rather than around the shared word "video" in a media plan document. reMKTR separates OLV and CTV into distinct lines from the first plan, specifically because collapsing them into one number is how a genuinely strong CTV result and a genuinely weak OLV result — or the reverse — end up averaged into a misleading middle.
